Description

Plug connector part with latching device

Technical Field

The utility model relates to a plug connector part for being connected with mating plug connector part.

Background

The plug connector part comprises a housing and a plug section arranged on the housing, which plug section can be plug-connected to a mating plug connector part in a plug-in direction. One or more electrical contact elements can be provided on the plug section, for example, for making contact with corresponding electrical mating contact elements of a mating plug connector part, wherein the plug section can be designed, for example, as a plug or a socket. The latching device serves to fix the plug connector part in a connecting position relative to the mating plug connector part and has a latching element for this purpose, which latches with the mating plug connector part in the latching position. Starting from the latching position, the latching elements can be adjusted in the actuating direction in order to be able to release the plug connector part from the mating plug connector part.

In such plug connector parts, a simple design, a latch which can be produced cost-effectively and can be handled comfortably by the user is basically required with the corresponding mating plug connector part in order to secure the plug connector part in the connected position relative to the mating plug connector part against unintentional detachment. Such a latch should be particularly simple and intuitive for the user, without requiring complex work steps for this purpose.

In the electrical plug connector pair known from DE 10 2014 115 A1, the plug connector part has latching elements which are connected to the housing in an articulated manner and which can be fixed in a latching position relative to the housing by screwing in the corresponding nut by means of screw elements.

SUMMERY OF THE UTILITY MODEL

The object of the invention is to provide a plug connector part having a latching device which can be manipulated particularly easily and intuitively for the user and which is secured in the latching position against unintentional release.

In this case, it is provided that the latching device has a locking element which is adjustable relative to the latching element, which locking element prevents an adjustment of the latching element in the locked position and which locking element releases the latching element in the unlocked position for an adjustment in the actuating direction from the latching position of the latching element, wherein the latching element surrounds the locking element at least in sections.

The fastening by means of screws can therefore be dispensed with, which can be constructed particularly easily and can release the fastening of the plug connector part to the mating plug connector part again, and furthermore can have a reduced weight. Furthermore, this arrangement enables a particularly space-saving design.

The plug connector part has a latching device for latching the plug connector part with a corresponding mating plug connector part in the connecting position. Thus, the plug connector part cannot be easily released, in particular unintentionally, from the mating plug connector part when the latching is established. The latching is established by latching elements which, in the latching position, engage, for example with latching projections, in corresponding latching openings of the mating plug connector part, so that the plug connector part is fixed relative to the mating plug connector part counter to the plugging direction and therefore cannot be released from the mating plug connector part counter to the plugging direction.

In order to lock the locking element in its locking position, a locking element is provided which is adjustable between a locking position and an unlocking position. For adjustment between the locked position and the unlocked position, the locking element can be moved relative to the catch element in such a way that the locking element is adjusted between an interaction with the catch element in the locked position and a release of the catch element in the unlocked position.

The latching between the plug connector part and the mating plug connector part can be released by moving the locking element relative to the latching element from the locking position into the unlocking position, so that the blocking interaction of the locking element with the latching element is cancelled.

The latching element surrounds the locking element at least in sections. For example, a section of the latching element extends on one side of the locking element, and a further section of the latching element extends on the other side of the locking element. The two sides are for example opposite sides. Optionally, the latching element completely, alternatively only partially, surrounds a part of the locking element.

The latching element and/or the locking element are formed in one piece. Alternatively, the latching element and/or the locking element can consist of a plurality of individual parts which are fixedly connected to one another.

Optionally, the locking element can be rotated about the rotational axis relative to the housing and/or relative to the latching element, in particular while maintaining the axial position (with respect to the rotational axis). In one embodiment, the locking element is rotatably received in a receiving opening of the housing. The rotatable mounting of the locking element, for example on the housing, enables a particularly simple and intuitive adjustment by the user.

In one embodiment, the locking element has at least one locking surface which is designed and provided to bring about the locking of the catch element. The locking surface interacts with the latching element, for example in the locked position of the locking element, optionally contacting the latching element. This makes it possible in particular to achieve a simple and at the same time robust locking of the latching position of the latching element. The locking surface is formed, for example, on a region of the locking element, which has a different shape from a circle in a cross section perpendicular to the axis of rotation.

In one refinement, the locking element has a bolt. The at least one locking surface can be formed on the pin. This enables a particularly robust design with a simple structure. In one embodiment, the locking element has a pin section that projects axially from the pin shaft and is rotatably mounted in a mounting opening of the housing. Optionally, the end of the pin is accessible from the outside. The pin section is arranged, for example, at the end of the pin remote from the end of the pin accessible from the outside. The diameter of the pin section is reduced, for example, relative to the pin shaft and the pin section is inserted into the bearing opening, so that the pin section is rotatably mounted in the bearing opening and is thus supported on the housing. On the other, externally accessible end of the bolt, for example, a tool engagement can be formed, by means of which a user can access the locking element with a tool, for example a screwdriver, in order to rotate the locking element about its rotational axis and thus adjust the locking element in the housing.

In one embodiment, the latching element has a web. In the locked position of the locking element, the locking surface of the locking element can be oriented toward, in particular in contact with, the web of the catch element, so that a movement of the locking element in the actuating direction is prevented. The tab is, for example, arranged between the locking element and an actuating section that can be actuated by the user.

Optionally, the locking element has at least one unlocking receptacle which, in the unlocked position of the locking element, faces the web of the catch element, so that the web of the catch element engages in the unlocking receptacle when the locking element is moved in the actuating direction. In particular, in this way a very secure locking of the latching position is achieved.

As an alternative or in addition to the abutment tab, the latching element has, for example, at least one locking spring (in particular two locking springs). In the locked position of the locking element, the at least one locking spring is optionally pushed into the locking receptacle of the housing by means of a locking surface of the locking element, in particular the spring is elastically tensioned. This enables a particularly flat design to be achieved. The direction in which the locking spring is pushed into the locking receptacle is oriented, for example, perpendicular to the actuating direction. Alternatively or additionally, the actuating direction and the axis of rotation are oriented perpendicular to one another. If the catch element comprises two locking springs, these are pushed, for example, in opposite directions.

According to one refinement, in particular when the latching element has one or more locking springs, the locking surface of the locking element is formed on a projection of the locking element. The movement, for example a rotational movement, of the locking element relative to the catch element brings the projection with the locking surface into contact with the locking spring and acts on the locking spring.

The locking element optionally has a latching contour which interacts in a latching manner with the housing, the component fixed to the housing and/or the latching element in the locked position and/or in the unlocked position of the latching element. The stop contour is, for example, a flattened or retracted region. The detent contour brings about a (tactilely recognizable) defined position of the locking element, so that the locking element can be placed more simply by the user into a clearly predefined position, which can correspond, for example, to the unlocked position and the locked position. Such a stop can be provided, for example, by a form-fitting section (e.g., formed on the pin lever and/or the pin section) which, in the locked position or the unlocked position, comes into contact with and/or engages a corresponding region (e.g., of the housing), respectively, so that the locking element is held in a latching manner in the locked position or the unlocked position relative to the housing section. The locking element can thus be moved by the user intuitively and comfortably between the locking position and the unlocking position, which are defined by the stops, respectively. In addition to intuitive actuation, it is thereby possible or additionally ensured that the locking element cannot be easily, at least not unintentionally, adjusted out of the locked position or the unlocked position.

In order to be able to adjust the latching element between the latching position and the release position, the latching element is preferably elastic in itself and can therefore be elastically deformed in such a way that a latching head, which is arranged on the latching element and has a latching projection, can be brought into or out of latching connection with a latching engagement (for example a latching opening) formed on the mating plug connector part in the event of elastic deformation of the latching element. Such a latching projection can be connected to the remaining latching elements, for example, by means of a latching arm. In particular, the latching arm can project from a base which is elastically deformable, so that the latching element can be moved with elastic deformation (in particular) between its latching position and its release position. The latching position of the latching element can in particular correspond to an unloaded, undeformed state of the latching element. Thus, the catch element is in the catch position when the catch element is not actuated. This enables, for example, the plug connector part to be placed onto the corresponding mating plug connector part in the plugging direction, namely in the case of an automatic establishment of a latching connection between the plug connector part and the mating plug connector part by means of the latching elements. In order to facilitate the latching, a latching bevel can be formed on the latching head of the latching element, for example, by means of which the latching head, when the plug connector part is plug-connected to the mating plug connector part, strikes against the housing section of the mating plug connector part and is thus (slightly) deflected out of the latching position until the latching element with its latching head engages with a corresponding latching engagement on the mating plug connector part in a latching manner and thus a latching connection is established between the plug connector part and the mating plug connector part.

The catch element can have an actuating section (for example in the form of an actuating head) that can be actuated by a user for adjusting the catch element in an actuating direction relative to the housing. The actuating head projects outwardly with respect to the housing, for example, so that a user can act on the actuating head manually or using a suitable tool, for example a screwdriver, in order to press the latching element in the actuating direction and thus to adjust the latching element from the latching position in the direction of the release position.

Optionally, the locking element is located between the latch arm (and/or the base) and the actuating section, relative to the actuating direction. A particularly space-saving design is thereby achieved, which provides space for further components, for example for screw connections for mounting shields, screens and the like.

Optionally, the latching element forms a receptacle. The locking element may be arranged to extend through the receptacle. This enables a particularly effective interaction between the catch element and the locking element in addition to a space-saving design.

In one embodiment, the plug connector part has a plurality of plug sections arranged in a row with respect to one another along an arrangement direction oriented transversely to the plug direction for plug connection with a mating plug connector part. Each plug section can be designed, for example, as a plug or a socket and can be connected in a plug-in manner to a corresponding mating plug section of a mating plug connector part, wherein one or more electrical contact elements can be arranged on each plug section for establishing electrical contact with the mating plug connector part. On the side remote from the plug section, the plug connector part can have, for example, a plurality of plug openings, through which the electrical conductors can be connected to the plug connector part in a clamping manner, for example by means of spring force connections or the like. In this case, each plug section can be provided with a plug opening for inserting an electrical conductor, for example, so that the electrical conductor can be connected to the electrical contact elements of the plug section via the plug opening.

The object mentioned at the outset is also achieved by a plug connector part. It is therefore proposed that the detent device has a locking element which can be rotated relative to the detent element about an axis of rotation relative to the housing while maintaining an axial position, with at least one locking surface which, in a locked position of the locking element, interacts with the detent element in such a way that an adjustment of the detent element is prevented, wherein, in an unlocked position of the locking element, the detent element is released from its detent position in the actuating direction.

The plug connector part can be implemented according to any of the embodiments described herein.

In the assembly of the plug connector part and the mating plug connector part, the mating plug connector part preferably has a corresponding number of mating plug sections for receiving the plug sections of the plug connector part. If the plug section of the plug connector part is shaped, for example, as a plug, the mating plug section of the mating plug connector part is correspondingly configured as a socket into which the plug section of the plug connector part can be inserted in the plugging direction in order to bring the electrical contacts of the plug connector part into electrical contact with the corresponding mating contact elements of the mating plug connector part.

Detailed Description

Fig. 1A and 1B show an embodiment of a plug connector part 1 which can be connected in a plug-in manner along a plug-in direction E to a corresponding mating plug connector part 2.

The plug connector part 1 has a housing 10 on which a plug section 11 with a plurality of plugs 110 projecting from the housing 10 in a plug-in direction E is arranged on one side. At least one electrical conductor is held in each case in the plug 110 for contacting an electrical contact element enclosed in the housing 10. The electrical contact elements are arranged such that, when the plug connector part 1 is plug-connected with the mating plug connector part 2, electrical contact with corresponding mating contact elements of the mating plug connector part 2 can be established.

The mating plug connector part 2 has a housing 20, on which mating plug sections in the form of plug openings of the socket type are formed. The plug 110 of the plug connector part 1 can be inserted into the plug opening in the plug direction E in order to establish an electrical contact between the plug connector part 1 and the mating plug connector part 2.

The plugs 110 of the plug connector part 1 are arranged in a row with one another along an arrangement direction a which is directed perpendicularly to the plugging direction E and can each be plugged-connected with a corresponding plugging opening of the mating plug connector part 2 along the plugging direction E. Fig. 1A shows the arrangement of the plug connector part 1 and the mating plug connector part 2 in the connected position, in which a plug 110 is inserted into the corresponding plug opening and thus an electrical contact is established between the plug connector part 1 and the mating plug connector part 2, while fig. 1B shows the plug connector part 1 and the mating plug connector part 2 before the plug connection (or after the plug connector part 1 has been released from the mating plug connector part 2).

The plug connector part 1 has latching means R which are arranged approximately centrally (viewed in the alignment direction a) on the plug connector part 1 and serve for latching the plug connector part 1 centrally to the mating plug connector part 2. The detent R can also be arranged eccentrically. For this purpose, the latching device R comprises a latching element 12;12' which can be brought into latching engagement with the latching opening 21 of the mating plug connector part 2 by means of a plug connection of the plug connector part 1 with the mating plug connector part 2.

Fig. 2 shows a part of the housing 10 of the plug connector part 1 and a part of the housing 20 of the mating plug connector part 2.

Fig. 2 shows the components of the latching device R of the plug connector component 1, in particular the latching elements 12 and the locking elements 13. In this case, it is provided that the locking element 12 at least partially surrounds the locking element 13. The detent element 12 comprises an actuating section 120, here in the form of an actuating head, which is arranged outside the housing 10 and comprises further sections arranged inside the housing 10. The locking element 13 is arranged inside the housing 10.

The function of the catch element 12 and the locking element 13 will now be explained in more detail with reference to fig. 2 to 3B together.

The latching element 12 comprises a latching arm 122, which projects from a base 123. At the end of the latching arm 122 facing away from the base 123, a latching projection 121 is formed, which can be brought into latching engagement with the latching opening 21 of the mating plug connector part 2.

When the plug connector part 1 is plugged onto the mating plug connector part 2 in the plugging direction E, the latching elements 12 serve to establish a latching connection between the plug connector part 1 and the mating plug connector part 2 by means of the latching projections 121. In this case, a latching ramp is formed on the latching projection 121, with which the latching projection 121 strikes a corresponding latching ramp on the end-side edge of the housing 20 of the mating plug connector part 2, so that the latching projection 121 is automatically deflected from the latching position in the actuating direction B when the plug connector part 1 is plug-connected to the mating plug connector part 2, and the latching projection 121 can thus be moved past the end-side edge of the housing 20 until the latching projection 121 engages with a corresponding latching engagement in the form of a latching opening 21 on the upper side of the housing 20 of the mating plug connector part 2, as can be seen from fig. 2.

A latching arm 122, on which a latching projection 121 is formed, projects through the front-side opening of the housing 10 and projects outwardly from the housing 10 on the side facing the mating plug connector part 2, so that the latching element 12 can be engaged with the latching opening 21 of the mating plug connector part 2 by means of the latching projection 121. At the other end, the latching element 12 has a latching projection 128 for holding the latching element 12 in the housing 10. The latching projections 128 engage in a form-fitting manner with the holding portion 107 of the housing 10.

As shown in fig. 2, for example, a latching opening 21 is formed in the region of the top side of each plug opening of the mating plug connector part 2. The latching elements 12 of the latching devices 11 of the plug connector part 1 engage with a plug opening arranged centrally on the mating plug connector part 2, with which plug 110 of no plug connector part 1 engages in the plug connection, so that the latching between the plug connector part 1 and the mating plug connector part 2 is established centrally by the latching devices 11.

Two side parts 124 project from the base 123 of the latching element 12, in particular in a direction perpendicular to the main direction of extension of the latching arm 122 (and to the plane in which the base 123 mainly extends). A spacing is provided between the side members 124. The actuating section connects the side parts 124 to one another. Furthermore, between the side parts 124, tabs 125 (or generally connecting sections) extend which connect the side parts 124 to one another. Therefore, the receiving portion 127 is formed by the tab 125, the side member 124, and the base portion 123. The locking member 13 is inserted into the accommodating portion 127. In particular, the locking element 13 extends through the receptacle.

The locking element 13 is accommodated in an accommodation of the housing 10 so as to be rotatable about the rotational axis D and is rotatable relative to the housing 10 about the rotational axis D. The locking element 13 has a pin 130. A bolt section 131 (with a reduced diameter) projects axially from the pin shank 130 at an axial end of the locking element 13. The pin section 131 is located in the bearing opening 108 of the housing 10 and is supported at the housing 10 by the bearing opening 108. The end face of the locking element 13, which is axially retracted relative to the pin section 131, rests around the bearing opening 108 on the inside of the housing 10, in particular on the front panel 100 of the housing 10.

At its axial end facing away from the pin section 131, the locking element 13 has a tool engagement 136, which is used in the example shown for a straight screwdriver. The end of the locking element 13 having the tool engagement portion 136 is rotatably supported in a further bearing opening of the housing, in particular of the back part 101 of the housing 10. The circumferential collar 133 projects in the radial direction with respect to the section received in the bearing opening and has a larger diameter. The flange 133 thereby rests against the inner side of the housing 10.

The locking element 13 is therefore supported on the housing 10 (and accommodated in the housing 10) in a rotatable manner about the axis of rotation D, but is (positively) fixed against translation relative to the housing 10 in both directions along the axis of rotation D. Thus, the locking element 13 can rotate relative to the housing 10 without performing a translational movement relative to the housing 10.

On the pin 130, unlocking receptacles 137 are formed on two opposite sides (alternatively, only on one side), each in the form of a flattened section. The unlocking receptacle 137 is a region of the locking element that is set back relative to the circumferential surface of the adjacent (here cylindrical) locking element 13.

Fig. 2 to 3B show the locking element 13 in the unlocked position, wherein the locking element 13 is oriented relative to the catch element 12 in such a way that one of the unlocking receptacles 137 is arranged adjacent to (in particular below) the web 125. In this case, a distance exists between the surface of the lug 125 and the unlocking receptacle 137, so that the actuating section 120 can be pressed in the actuating direction B (downward), wherein the lug 125 is introduced into the unlocking receptacle 137. The latching arm 122 is correspondingly moved along and displaced from a latching position into a release position, in which the latching projection 121 is pulled out of the latching opening 21 of the mating plug connector part 2.

For the simplest possible latching of the plug connector part 1 with the mating plug connector part 2, the latching arm 122 is pretensioned into the latching position, for example by means of a spring, or, as in the example shown, by means of a resilient end section of the base 123 of the latching element 12, which end section is fixedly connected to the housing 10. The actuation of the actuating section 120 against the pretensioning force displaces the latching element 12 into the release position. The slot 104 in the housing 10 allows the side member 124 to be pushed therein and thus the latch arm 122 to pivot, the side member 124 extending through the slot 104.

In order to lock the catch element 12 in its catch position, the locking element 13 can be rotated further into the locking position. In the locked position, locking surface 132 is disposed adjacent tab 125. The locking surface 132 has a larger radius with respect to the rotational axis D than the unlocking receptacle 137. In this embodiment, the locking surface 132 is formed by an unretracted portion of the circumference of the pin 130.

If the locking surface 132 is arranged adjacent to the web 125 (here below it), it has a smaller distance from it than the surface of the unlocking receptacle 137 in the unlocking position. Optionally, the locking surface 132 contacts the tab 125 in the locked position. Thus, in the locked position, the locking surface 132 prevents the latch arm 122 from moving from the latched position to the unlatched position.

The locking element 13 can thus be rotated relative to the housing 10 and relative to the catch element 12 between a locked position and an unlocked position. The locking element 13 comprises two opposing locking surfaces 132 and two opposing unlocking receptacles 137. The locking surfaces 132 and the unlocking receptacles 137 are arranged alternately, i.e. offset by 90 ° each, when viewed about the axis of rotation D. Thus, one transition between the locked position and the unlocked position is made around a quarter of the rotation axis D.

In order to enable tactile feedback of the position state to the user and to provide a defined position, the locking element comprises a stop contour 138. The latching contour 138 is formed here in the form of a recess on the circumference of the pin 130. In the example shown, the stop contour 138 is shaped on an axial end adjacent to the bolt section 131. The latching occurs in that one or more of the latching contours 138 latch with a section of the housing 10. For example, two opposite inner walls of the housing 10 or the spring-elastic regions arranged thereon have a distance from one another which is smaller than the diameter of the cylindrical circumference of the pin 130, but is approximately as large as the diameter of the locking element 13 on the latching contour 138. Optionally, the housing 10 has a profile that matches the stop profile 138. In the present case, one latching contour 138 is provided on the locking element 13 for each locking surface 132 and unlocking receptacle 137, respectively, to be precise in the example shown, each latching contour 138 being provided in the same angular position about the axis of rotation D as the respective locking surface 132 or unlocking receptacle 137. The stop contour 138 additionally prevents an unintentional rotation of the locking element 13 out of the locking position or the unlocking position.

As can be seen in particular from fig. 2, the arrangement of the catch element 12 and the locking element is such that the catch element 12 at least partially surrounds the locking element (in the example shown, it is itself accommodated), resulting in a particularly space-saving design. The locking element 13 is arranged between the actuating section 120 on the one hand and the base 123 and the latching arm 122 on the other hand, and not for example below the latching arm 122. Thus, the area under latch arm 122 may be used in other ways, in this example to screw the shield to threaded hole 105.

Fig. 4 to 6B show an embodiment of a latching device R for plugging a connector part 1, which largely corresponds to the latching device described above. In contrast, however, the detent element 12' does not have a web (apart from the actuating section 120 and the base 123) connecting the side parts 124. Furthermore, the section of the circumferential surface of the pin 130 that is not retracted serves as an unlocking receptacle, but rather projections project radially outward from the circumferential surface section of the pin 130, which projections form a locking surface 132'.

On the catch element 12', in the example shown on its side part 124, a locking spring 126 is formed, wherein the locking spring is cut off (normally such a locking spring 126 would also be sufficient). The outwardly projecting locking surfaces 132 'can be advanced by rotation of the locking element 13' against the locking springs 126, so that these are resiliently urged outwardly by the springs. The housing 10 (here on a side part of the front panel 100) comprises a lock receptacle 109 (in the form of a groove, respectively) for each lock spring 126. When these locking springs 126 are pushed outward, they engage into the corresponding locking receivers 109. The locking receiver 109 is provided such that the engagement is possible only in the latching position of the latching element 12', so that by adjusting the locking element 13' into the locking position, the latching element 12' is locked in the latching position.

The locking surface 132' does not have a radial step, but rather protrudes continuously with respect to the circumference of the pin shank 130, so that the locking spring 126 can be displaced outwards without being placed on a ridge.

Fig. 6A shows the unlocking position of the locking element 13', in which the locking spring 126 is not engaged in the locking receiver 109. Fig. 6B shows the locking position of the locking element 13' and it can be seen that the locking spring 126 engages lockingly in the locking receiver 109.

Referring to fig. 7, it is shown that it may also be sufficient to connect the latch arm 122 to a single side wall 124 of the actuating section 120. The locking element 13 'is partially surrounded by the catch element 12'. Correspondingly, the catch element also comprises only one locking spring 126.

The idea on which the invention is based is not limited to the embodiments described above, but can in principle also be implemented in completely different types of ways.

Latching devices of the type described here can in principle be used on completely different plug connector parts and are not limited in this respect to the type of plug connector parts shown in the figures.
